The idea is that the NV monocular will amplify the light from the telescope which exits the eyepiece will make you see much better the DSO light for which we use averted vision.
In all this experiment I'm not considering the IR emitter of the NV monocular.

But I'm not from US ... so I'm only able to try the solution presented by me above.

I knew the NV + telescopes must work somehow.

I don't want to use a Mallincam due to cost and the lack of a lcd screen (I don't want to drag outside a separate TV/display + cables for Mallincam, especially in winter), but I thought the NV Monocular could be like a Mallincam + integrated LCD.
